Ten people, including one from the San Antonio area, were arrested Wednesday on hazing charges in the death of a Louisiana State University fraternity pledge whose blood-alcohol content was more than six times the legal limit for driving, officials said.

One of the 10 — Matthew Alexander Naquin, 19, of Fair Oaks Ranch — also faces a felony negligent homicide charge in the death of freshman Maxwell Gruver, who was trying to join Phi Delta Theta. Naquin is the only one facing a felony charge; the hazing charges are misdemeanors.

Both fraternity members and pledges felt Naquin was “taking it too far” and had specifically “targeted” Gruver, 18, of Roswell Georgia, during the Sept. 13 hazing ritual, according to an arrest affidavit, which was released Wednesday.

About 18 to 20 pledges, including Gruver, had received text messages calling them to the home around 10 p.m. Sept. 13 for “Bible Study.” During the ritual, according to the affidavit, active members quiz pledges on details about the fraternity and force them to drink if they answer the questions incorrectly.

When the pledges arrived, Naquin yelled, “are you ready for Bible Study,” according to the affidavit.

The pledges were allegedly sent upstairs, where another fraternity member threw mustard and hot sauce on them. With a single strobe light flashing and loud music playing, the pledges were told to line up against the wall, police said.

Naquin is accused of forcing pledges to drink 190-proof liquor. Active members told Naquin and the other member to “cut it out” because their actions were “getting out of hand,” according to the affidavit. One fraternity member said he warned Naquin and the other member to “slow it down” several times, to no avail.

Naquin seemed to target Gruver, whom he was upset with for being late to events, pledges told police. In addition, Gruver kept messing up the Greek alphabet and that Naquin forced him to drink each time he made a mistake, one member told police. While most pledges only had to take three to four swigs of the powerful liquor, Naquin allegedly forced Gruver to take 10 to 12 drinks.

“During the course of the interviews, the recurring statement was that Naquin was the most aggressive and in charge of the hazing event,” the affidavit said.

On the morning of Sept. 14, Gruver, an aspiring sportswriter, was taken by two fellow students to a Baton Rouge hospital, where he was declared dead. He had passed out on a couch at the fraternity house around midnight. Several fraternity members said they had checked on Gruver “throughout the night,” police said. But in the morning, when friends returned to the house, he was unresponsive and they couldn’t tell if he was breathing. That’s when the friends decided to take him to the hospital.

A toxicology report on Gruver revealed that his blood alcohol content was 0.495 percent, more than six times the legal limit for driving, and that he had aspirated vomit into his lungs. The cause of death was “acute ethanol intoxication with aspiration,” according to the East Baton Rouge Parish Coroner’s Office.

A lawyer for Naquin, John McLindon of Baton Rouge, declined to comment on these charges “out of respect for (Gruver’s) family.”

“Let’s just wait until the evidence comes in,” he said.

“The ramifications of hazing can be devastating,” LSU President F. King Alexander said in a statement. “Maxwell Gruver’s family will mourn his loss for the rest of their lives, and several other students are now facing serious consequences — all due to a series of poor decisions.”

Negligent homicide is punishable by up to five years in prison in Louisiana, the report said. Hazing is punishable by up to 30 days in jail.

A student accountability office also is conducting an investigation that could lead to disciplinary action, according to Ernie Ballard III, LSU’s media relations director. Under Louisiana law, any student convicted of hazing must be expelled.

The death resulted in the national office closing the LSU chapter and a temporary hiatus on all Greek life activities at LSU. On Oct. 4, fraternities and sororities were permitted to resume activities but with new limits. The university also convened a task force to study Greek life.

All the suspects were associated with Phi Delta Theta; one left school after Gruver’s death, and eight are still active students, university spokesman Ernie Ballard said. All 10, ages 18 to 21, turned themselves in to LSU police on Wednesday.

The other nine suspects are Louisianians Zachary Castillo of Gretna, Sean-Paul Gott of Lafayette, Sean Pennison of Mandeville, Hudson Kirkpatrick of Baton Rouge, Elliott Eaton of New Orleans; Patrick Forde of Westwood, Massachusetts; Nicholas Taulli of Cypress; Zachary Hall of Charlotte, North Carolina; and Ryan Isto from Canada.

East Baton Rouge District Attorney Hillar Moore said his office will present evidence to a grand jury and could seek additional charges.

Investigators are studying text messages sent and received by the fraternity members and pledges, have learned of possible videos and have seized a duffel bag filled with beer cans, bottles of liquor, a glass smoking pipe and a “pledge test,” according to search warrant requests and results.

Gruver’s death followed several other highly publicized deaths in recent years, also leading to criminal charges and the closure of fraternity chapters.

Timothy Piazza, an engineering student at Pennsylvania State University from Lebanon, New Jersey, died Feb. 4 after a night of hazing. That led to strict new regulations on Greek life, including a prohibition on liquor, kegs and all-day parties. In May, 18 students were charged in Piazza’s death — including eight with voluntary manslaughter — but the more serious charges were thrown out by a judge.

Also in May, four men pleaded guilty to voluntary manslaughter in connection with the 2013 death of Chun Hsien Deng, a student at Baruch College in Manhattan who was knocked out and killed during a hazing ritual that occurred on a fraternity trip to Pennsylvania.
